Kahului Harbor in Maui is an exposed reef break that has consistent surf. Winter is the favoured time of year for surfing here. Offshore winds are from the south with some shelter here from east winds. Clean groundswells prevail and the best swell direction is from the north northeast. Reef breaks provide lefts and rights. Good surf at all stages of the tide. When the surf is up, it can get quite busy in the water. Beware of urchins, rips, rocks, locals, pollution and sharks.
